Signage Rules: Martinez vs Walnut Creek

Martinez prohibits exterior signage advertising home-based businesses in residential zones. The Zoning Ordinance's home occupation standards are explicit that the business must not be visible from the public right-of-way, which includes no window signs, yard signs, banners, or exterior lighting that identifies the business. This rule preserves residential neighborhood aesthetics and is strictly enforced.

Home occupations in Walnut Creek are prohibited from having any exterior signage advertising the business. The home must retain its residential appearance from the street — no signs, banners, window lettering, illuminated advertising, or similar displays visible from outside the dwelling.
